Abstract
A controller includes a primary controller and a secondary controller to control switching of a power switch and a supplemental switch, respectively, coupled to an energy transfer element, e.g. an energy transfer element of a power converter. A ZV drive circuit are coupled to generate a ZVS signal that enables a ZV switch to store energy in the energy transfer element. The energy stored in the energy transfer element is coupled to reduce a switch voltage across the power switch prior to a next ON section of the primary drive signal. The secondary drive signal is generated in response to the drive signal and the ZVS signal.
